CHECK-CONTROLLED MECHANISM.

esaaio.

To all whom it may concern:

Be it known that I, EUGENE T. TURNEY, a citizen of the United States,residing at Rock Island, in the county of Rock Island and State ofIllinois, have invented certain new and useful Improvements inCheck-Controlled Mechanism, of which the following is a specification.

This invention relates to improvements in check controlled mechanism andthe primary object of the invention is to provide an improved device ofthis character for closing the circuit of an operating mechanism, suchas a motor or the like, and im proved means for locking the circuitcloser against movement.

A further object is to provide improved means for releasing themechanism or breaking the circuit.

A further object is to provide an improved device of this characterwhich will be simple, durable and cheap in construction, and effectiveand efficient in operation.

To the attainment of these ends and the accomplishment of other new anduseful ob jects, as will appear, the invention consists in the featuresof novelty in the construction, combination and arrangement of theseveral parts hereinafter more fully described and claimed and shown inthe accompanying drawing, illustrating an exemplification of theinvention, and in which Figure 1 is an elevation of an improved deviceof this character constructed in accordance with the principles of thisinvention and with one face of the inclosing casing removed, taken online 11 of Fig. 2. Fig. 2 is a sectional view taken on the line 22 ofFig. 1.

Referring more particularly to the drawing and in the presentexemplification of the invention, the numeral 10 designates an inclosingcasing which may be of any desired size and configuration andconstructed of any suitable material, and 11 designates a removableclosure which constitutes one wall of the casing.

Pivotally supported within the casing, and intermediate its ends is alever or mem- Specification of Letters Patent.

ber 12 which is preferably arranged adjacent the upper portion of thecasing and projecting laterally from one side thereof is an arm orextension 13, which is provided with a suitable metallic portion 14;.Suitably supported adjacent the arm or extension 13 are spaced contacts15, to which are connected suitable conductors 16 which lead from asource of supply 17 and have operative connection with a suitable motor18. The arm or extension 13 is adapted to be moved into and out ofengagement with the contacts 15 by the movement of the lever or member12 about its point of pivotal support 19, and a suitable spring 20 isprovided which engages the lever or member 12 to one side of the pivotthereof for normally holding the metallic portion 14; of the arm orextension 13 in engagement with the contacts 15.

A latch 21 is pivotally supported by one extremity as at 22 adjacent oneextremity of the lever or member 12 and is provided with shoulders 23,24, the shoulder 23 being adapted to be engaged by the free extremity ofthe member or lever 12 to limit the movement of the latter about itspoint of pivotal support 19, when the metallic portion 14L of the arm orextension 13 is in engagement with the contacts 15. A suitable yieldingmember or spring 25 is provided and engages the latch 21 to normallyhold the latter elevated so that the shoulder 23 will be held in thepath of movement of the free extremity of the lever or member 12 in onedirection, and if desired, a stop 26 may be arranged within the casingto limit the upper movement of the latch 21 under the influence of theyielding member or spring 25. The spring 20 serves to hold the freeextremity of the lever or member 12 against the shoulder 23 of the latchand the yielding member or spring 25 tends to normally hold the shoulder23 in the path of movement of the lever or member in one direction.

When the arm or extension 13 is raised so as to move the metallicportion 1 1 out of engagement with the contacts 15 the lever or member12 will be rocked about its point of pivotal support 19 to move the treeextremity thereo't' away from the shoulder 23 and toward the shoulderits member 12 moves against the tension of the spring 20, the yieldingmember or spring 25 will raise the latch 21 about its point of pivotalsupport 22 to cause the shoulder 24 to assume a position in the path ofmovement of the tree extremity of the lever or member 12 in the oppositedirection so as to lock the metallic portion 1 1 out of engagement withthe contacts 15 to break the cir' cuit.

Any suitable means may be provided for automatically raising the arm orextension 3 to rock the lever or member 12. A suitable and elticientmeans for accomplishing this purpose comprises a bellows or pneu matic27, which is adapted to be exhausted through a suitable tube or pipe 28in any desired manner, not necessary to illustrate. The movable member29 of the bellows may be connected to the tree extremity of the arm orextension 13 in any desired or suitable manner, such as by means of aconnecting member 30, one end or which is connected to the movablemember 29 and the other end is preferably detachably connected to thearm or extension so that when the bellows is collapsed by means ofexhausting the air therefrom, the movable member 29 will be raised andwill move the lever or member 12 about its point of pivotal support, atthe same time the spring or yielding member 25 will automatically raisethe latch 21.

The closure 11 of the casing is provided with a suitable check slot 31and secured to the inner face of the closure is a check chute 32, whichis adapted to receive the check passed through the slot 31. This chute32 is arranged above the free extremity of the latch 21 in a differentvertical plane and is of such an inclination that when a check of theproper size and weight is deposited therein, the check will receivesutlicient momentum as it passes down the chute to throw it against thetree extremity 33 of the latch 21 and being of the proper weight willdepress the latch 21 against the tension of the yielding member orspring 25 to release the lever or member 12 and when the latter is soreleased, the spring 20 will rock the lever about its point of pivotalsupport 19 until the free extremity engages the shoulder 23 of thelatch. At the same time the arm or extension 13 will be moved intoengagement with the contacts 15 and the movable member 29 or the bellows27 will be adjusted through the medium of a connecting member 30 to fillthe pneumatic with air.

Obviously this improved check controlled the lever orl mechanism may beemployed for any desired or suitable purpose where it is necessary tocomplete an electric circuit or otherwise but this improvement isparticularly adapted for use for playing attachment for musicalinstruments oi the type described and claimed in my application forLetters Patent Serial No. 331,740, filed in the United States PatentUliice August 23, 1906.
